Title:
METHOD FOR PREPARING METHANOL BY MEANS OF HYDROGENATION OF CARBON DIOXIDE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/087686
Kind Code:
A1
Abstract:
Provided in the present application are a method for preparing methanol by means of hydrogenation of carbon dioxide and the use thereof. The method comprises the following steps: bringing reaction raw gas into contact with a catalyst, and grinding same to realize the reaction of the reaction raw gas under the action of the catalyst to obtain methanol. According to the method for preparing methanol by means of hydrogenation of carbon dioxide provided in the present application, mechanical grinding is matched with a common catalyst for a catalytic reaction, such that the reaction temperature is remarkably reduced, the conversion rate of carbon dioxide and the selectivity of methanol are improved, and the service life of the catalyst is prolonged.
